RUDOLPH VUILLEUMIER, OF NEW ROCHELLE, NEW YORK, ASSIGNOR TO SAFETY CAR HEATING & LIGHTING COMPANY, A CORPORATION OF NEW JERSEY.

FAN APPARATUS.

To all whom t may concern.'

Be it'knovvnv that I, RUDOLPH VUILLEU- MIER, a citizen Aof the United States, and residing at New Rochelle, in the county of Westchester and State of New York, have invented a new and Improved Fan Apparatus, of which the following specification is a full disclosure.

This invention relates to fan apparatus and related devices and with regard to certain more specific features thereof to a fanarrangement for railway cars.

One of the objects thereof is to provide apparatus ofthe above nature in which the discharge from the fan is efficiently directed to the desired point.

Another object is to provide apparatus of the above type in which a desired form of current of air is established without material loss in energy.

Another object is to provide apparatus of the above type in a railwaycar in which the discharge is so directed and of vsuch nature as effectively to meet the practical conditions 'of such use.-

Other objects will be in part obvious from the annexed drawings and in part indicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the features of construction, combinations of parts, and in the unique relations ofthe members and in the relative proportioning and disposition thereof; all as more completely outlined herein.

' To enable others skilled in the art so fully 'to comprehend the underlying features thereof thatv they may embody the same by the numerous modifications in structure and relation contemplated by this invention, drawings depicting a preferred form have been annexed .as a part of this disclosure, and in such drawings, like characters of reference, denote corresponding parts throughout all the views of which Figure 1 is a sectional elevation of a fan and relatedl devices. Fig. 2 is a sectional plantaken on the line A-A of Fig. 1. Fig. 3 is a similar-view taken on the line B-B of Fig. 1. Fig. 4 is a'diagrammatic sectional elevation of a railway car provided with apparatus of this nature.

Referring now to Fig. 1 of the drawings, there is shown at 1 a car roof, having an Specification of Letters Patent.

AppIication led August 22, 1914. Serial No. 857,998.

' having the usual cured thereto a beveled pinion 40, the tions of whichwill be hereinafter described.

inner sheathing 2. Bolted to this roof 'as at 3 and 4 is a supporting casting 5 com` prising arms 6 connecting the rings 7 and 8. An electric motor 9 is mounted upon this castlng by means of the arms 10 and screws 11, the latter passing throughlugs 12 in the motor casing. The upper portion 13 of this casing, -together with the brushes 14 and other parts mounted thereon, maybe moved as a unit by first taking out the screws 15. securing it through lugs 16 to the lower casing. The shaft 17 of this motor is vertically disposed and journaled in bearings A18 and a removable cap 19 protects'the parts from dust yet affords ready access to the bearings. This motor is mounted to extend within an outer housing 20 which projects through the car roof as at -21 and is provided with an opening 22 having an adjustable shutter comprising the slats 23 whlch are connected to swingas a unit and are controlled from a link 24 within the car leading to the shutter through a bell-crank lever 2 5-and link 26. A suitable conduit 27 is provided in the housing for' the electric conductors leading to the motor.

Mounted uponshaft-17 is a rotary fan 28 inclined blades and adapted to draw air either through the opening 22 or between the arms 6l and dischargeit downwardly. The lower endof shaft 17 terminates in a coupling 29 of the Oldham type, having the innerfitting tongue and groove 30 to allow for Inisalinement of the .shaft with a worm shaft 31. which is driven'therefrom. The latter shaft is journaled inthe bearings 32J and 33 and carries worm 34 which. meshes with the worm-wheel 35 positioned upon a cross-shaft 36. A pair of spur pinions 37 and 381 vdrive a radial shaft 39 havin se- `rotation of the deflector is accomplished by means of a circular rack 45 havin beveled teethl meshing with and driven rom the piniony 40. To take up the effect of the thrust of this pinion and guard against tilting of the de'lector there is provided an idle guide pinion 46 likewise meshing wrth the rack 45 and rigidly mounted u pon the arm l47. In this manner, as the motor 9l is set in operation, the worm 34 by means of the gearing above described4 slowly rotates the deliector 41 about an axis substantially -in alinement with the motor shaft.

Mounted upon the supporting spider 43 is a lamp socket 48 having secured thereto by a spring clip 49 a lamp shade 50 and having. electrically connected H therein a lamp bulb 51. l l

As will bey seen by reference to Fig. 4 of the drawings, the above apparatus is so pos itioned that the lamp 51 is properly disposed with respect to the car seats 52 and by means of deflector 41 the discharge from the fan is directed toward these seats and eiiiciently used. This is accomplished, moreover, with a single supporting device. It will also be noted that by the use of the y inlet port 22 the ventilation of the car is the rotating movement of the deflector as centrifugal action tends to throw the aircurrents outwardly. These currents of air are thus directed intermittently upon the passenger, this form of air-current being considered advantageous in fan construction. The air inlet at 22 may be adjusted to'any desired degree and all of the parts, by the devices shown, are readily assembled or removed for purposes of inspection or repair.

It .will thus be 'seen that there is rovided apparatus by which theobjects o this ini vention are achieved.

As many changes might be made in the above construction and as many apparently different embodiments of this invention could be made without departing from the scope of its several features, it is intended that all matter described above or shown in the?acc'ompanying drawings shall be inter.

preted as illustrative and not in a llimiting sense.

Having thus revealed this invention, I claim as new and desire to secure thefollowingcombinations of elements, or equiva- Maase? lents thereof, by Letters Patent of the United States 1. In apparatus of the character described in combination, an electric motor, a downwardly directed fan rapidly rotated by said motor, means adapted to throw air from the said fan in a current in a direction outwardly inclined from a vertical axis and means driven from said motor adapted to give a slow relative rotary movement between said fan and said first means aside from the rotation of said fan, and thereby cause said outwardly inclined current to r0- tate about said axis.

2. In apparatus of the character. described, in combination, a fan; a deflecting device in the path of discharge from said fan shaped to throw air discharged from said fan in a current in a predetermined direction; and means adapted positively to rotate said device and thereby said current in a predetermined path.

3. In apparatus of the character described, in combination, a fan; a source of power from which said fan is driven; a deflecting device in the path of discharge from said fan shaped to throw said discharge in a path inclined to its original direction; and means driven from said source of power adapted positively to rotate said device about an axis substantially parallel with the direction of discharge of said fan and at a speed slower than that of said fan.

4. In apparatus of the class described, in combination, an electric motor mounted with its shaft substantially vertical, a fan driven from said motor and formed and mounted to rotate about a substantially vertical axis and discharge the air downwardly,

a support, a deflecting device mounted upon said support to rotate about a substantially vertical axis, said deecting device being provided with inclined members adapted to receive the air discharged from said fan and throw it outwardly, and means driven from said motor adapted positively to rotate said delecting device at a slower speed than that of said fan.

scribed, in combination, a source of power; a fan drlven from said source of power and positioned to drive the air downwardly; a de'lecting means below said fan adapted to a fan driven from said source of power and;`

receive the air therefrom and deflect outwardly; and means independent of the air discharged from said fan adapted to rotate said deflecting means. y

8. In apparatus of the character described, in combination, a source of power;

flecting means.v

spect to the axis of said discharge; and means adapted to rotate positively said deflecting device.

10. In apparatus of the character described, in combination, a source of power; a fan driven from sald source of power and -positioned to drive the air downwardly; de-

fle'cting means below said fan adapted t0 receive the air therefrom and deflect it outwardly, said deflecti'ng means comprising a plurality' of members inclined with respect one to the other; and means driven from said source of power adapted to rotate said de- In witness whereof, I hereunto subscribe my name, as attested by the two subscribing witnesses.
